1.6 Non-reactive Bus Terminals
Note
Use of non-reactive Bus Terminals in safety applications
If a Bus Terminal is described as non-reactive, this means that the downstream terminal
behaves passively in a safety application (e.g. in the case of the all-pole switch-off of a po-
tential group).
In this case the terminals do not represent an active part of the safety controller and do not
affect the Safety Integrity Level (SIL) or Performance Level (PL) attained in the safety appli-
cation.
For details, please refer to chapter 2.17f in the TwinSAFE application manual.
Attention
Pay attention to the hardware version
Please pay attention to the information about the hardware version and non-reactivity of the
respective Bus Terminal in the chapters "Technical Data" or "Firmware Compatibility"!
Only terminals with the appropriate hardware version may be used without the attained SIL/
PL being affected!
